IMPROVEMENT IN WH EEL.VEHICL..S.

Specification forming part of Letters Patent No. 35,017, dated April722i, i802.

Figure l is a plan or top view of the run I ning-gear of a wheel-vehiclewith my imtion of the same, taken in thelinefr, Fig. l.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an improvement in the manner of attaching thefront axle of the vehicle to the perch or to iixtures ecnnected to thebody, as hereinafterfully shown and described, whereby the vehicle maybe turned within a small compass, .the front wheels admitting of beingso cramped or turned as to insure the result stated and still allow arequisite space between the front and back wheels for the attachment ofproper steps to the body of the vehicle, and also admit of the front andback wheels being placed nearer together than usual without coming incontact when the frontwheels are turned or cramped.

To enable those skilled in the art to fully understand and construct myin veution,l will proceed to describe it.

A represents the back axle of a wheel-vehicle, and B the reach or perch,which attached atits back end to the back axle, A, and at its front endto a bolster, C, as shown in Fig. l. The bolster C has two lugs orprojections, o a, extending from its front side at right angles, onenear each end, and in these lugs or projection the ends of a shaft, D,are secured. The shaft D is at right angles with the perch B, and onsaid shaft there is placed a slide, E, provided with a pendent pintle,b, which passes loosely through the front parts of two eyes, c c', andhas a head, d, on its lower end, as shown in Figs. 2 and 3. The

eye c is attached to the front axle, F, at its center, and the eye c isin the front part of a bar, d', which is secured transversely to theunder side of the front axle, F, and has its back end fitted loosely ona pintle, e, attached to. the under side of a slide, G, on a shaft, Il,which is parallel with the perch B, and has its ends secured in pendantsf f of the perch. (See Fig. 3.) The upper end of the slide G isconnected by a pivot, dx, with a semicircular plate, I, which isattached to the upper surface of the front axle, F. (See Fig. l.) Thefront axle has thills or a draftfpole attached to it in the usual or inany proper way.

From the above description it will be seen that when the `vehicle isdrawn along, the pull will be on the slide E and shaft D,

g the pintle b forming the connection between provement applied to it;Fig. 2, a front view of a portion of the same; Fig. 3, a vertical secthefront axle, F, andthe slide E, and it will also be seen that when thefront axle, F, is turned the slide E will move on the shaft D either tothe right or left, while the slide G will move forward on its shaft ll.This movement of the slides It G, as indicated in red in Fig. l,produces a very importa-nt result. It causes the front axle, F, to turnfrom a back center, which is the pivot ax, that connects thesemicircular plate I with the slide G, and it also causes said center axto move forward while the' axle F is turning.

vConsequently a quick cramping position of the front axle is obtainedfrom a back center, while the disadvantage hitherto attending a fixedback center-to wit, the bringing ol the front wheels suddenly in contactwith the body of the vehicle-is avoided; and hence by my invention thefront and back wheels may be placed nearer together than usual, where afixed back center is used, without the front wheels comin in contactwith the back wheels or with the body of the vehicle, and all necessarysteps maybe attached to the vehicle without the front wheels coming incontact with them.

I do not claim attaching the front axle of a vehicle to its perch orreach by Ia back center, or, in other words, bya king-bolt placed backof the axle, in order to obtain aquick cramping or turning movement ofsaid axle, for this ha-s been previously done; but

.I do claim as new and desire to secure b v Letters Paten t Theconnecting of the front axle, F, to the perch or reach B by means of thetwo slides E G, placed, respectively, on the shafts D II, and connectedwith the axle F, substantially as shown, for the purpose herein setforth.
